**Author's Note:**

> I'll be honest... this is practically a re-write of my previous (and bad) Didn't gain LOVE.  
> (AN: Also I imagined the fireplace would be where the tv is but for today, Sans had pushed the tv over to the side so they could use it). Anyway! I hope this time it is better paced and a lot more scrummy~

Coming home from work, Papyrus came in the door whilst being sure to remove any snow that had gathered on his hoodie. There was a snow storm during this time of year. Though thanks to the many resets, Papyrus made note of the day and was sure that both he and Sans were home and suffered no harm. Just one of the many positives of remembering resets.

Sans was already home as it was his day off, much to Papyrus' relief. He could see that his brother putting wood in the fireplace in an attempt to warm up the house a bit more.

"Hi Papy!" Sans smiled now noticing his brother and giving him a hug. _As usual._

"hey bro," Papyrus chuckled as he rubbed the top of his brothers head.

The two hugged for a while, after all they felt most content and warmth when being together. Although Papyrus had noticed in this timeline in particular, that Sans seemed to be clingy as Papyrus was (admittedly) spending more time with Muffet, so whenever Sans got the chance then he would hold him close never wanting to let go. _As though he'd been away for weeks._

Upon clearing his throat, Sans looked up at Papyrus and pulled back, "i got you somethin',"

He smiled as Sans curiously watched Papyrus lift up his jumper, slightly exposing his ribs to then pull out a black case with a white sticker placed on top, which Undyne had written on to remember the title of the movie.

"it's kissy kissy cutie 3 lovey dovey doo dah? bit strange i know but undyne said that these films are fun to watch so I thought maybe you'd want to have a movie night?" Papyrus winked; knowing full well that his brother would be thrilled to spend any time with him like this, as he in return also enjoyed doing with Sans.

But true to Sans' never ending energy he practically shook with joy as his expression got more excited and giddy with every word coming out of the tall skeleton. That he low key desperately craved affection from.

"Oh my gosh! really?!" Sans squeaked his hands rubbing against one another in an attempt to calm down, which hardly ever really worked, but then it didn't matter to Papyrus.

He nodded and braced himself as he gained another hug but with twice as much force; nearly knocking him over, but definitely taking his breath away with an 'oof', despite his small frame his brother was awful strong.

Papyrus hugged his brother back by wrapping his arms around him pulling him close, even pecking the top of his head. He felt his brother nuzzling into his chest muttering about something but he couldn't quite hear. Regardless it was always comforting for Papyrus, his brother was alive for another day.

A slight grumble from his stomach, non-existent or not, reminded his brother of the food he was cooking.

He tried pulling away from Papyrus when he realised that he wasn't letting him go, "Papy I need to check on dinner!"

Papyrus sighed as he reluctantly let him go, watching as he dashed off into the kitchen. But he couldn't help but be curious, as the aroma was different from the usual taco-like smell so he followed behind and watched as Sans moved around, stirring the pot then checking whatever was cooking in the oven at a low temperature (well, low for Sans anyway) and then jumping slightly as he realised he's being watched.

"what'cha makin' in there?" Papyrus asked, his gazed now fixed in the direction of the simmering pot.

"It's speg... spagehti... pasta!" Sans smiled and posed dramatically.

_Can he be any cuter?_

"pasta huh?" Papyrus grinned as the smell was divine and yet oddly familiar.

"Now I know that you love~ my tacos but I figured that maybe we could try something else" Sans grinned as his brother looked ever so happy, making himself feel rather ecstatic. So rare was it to see his brother look genuinely interested in what he was doing.

"yeah bro this smells so good" Papyrus said pulling himself away from the pot, "is it ready?"

"Should be" Sans said turning off the cooker.

The pasta was already set to the side all that was needed was the sauce. Papyrus was really looking forward to eating as he volunteered to set out the table much to Sans' delight.

Sans on the other hand took out the bread with garlic in it (a strange food that humans eat with their pasta supposedly!) and grabbed plates for both he and his brother. Setting Papyrus' aside and grabbing his own putting on a fair amount of pasta on it along with the sauce. Then sprinkling a little cheese over the top, it looked good to Sans and had healthy vegetables in it too.

He sat down taking his plate and the one with the garlic bread on it and sitting down at the table, waiting eagerly for his brother to return. When he did he was surprised to say the least. Papyrus' plate was almost over flowing with the stuff, never before has he seen his brother pile so much food onto his plate.

He sat down across from Sans, taking his fork and digging into his meal. It was a joy for Sans to see his brother for once, thoroughly enjoying something that he's made. Sure he loved his tacos, who doesn't? but maybe this meal is just a little more special, perhaps he could use this as a tool of getting his brother to stop being lazy!

"you not eating bro?"

Sans nodded and ate his meal too. It was pretty good if he should say so. This will definitely be another meal choice in future.

Their was little to no talk between the two as they ate but that was because Papyrus was enjoying his meal and Sans was more than happy watching him eat.

"I guess i'll have to make more sometime?" Sans smiled, his hands holding his head as he rested.

Papyrus held a thumbs up, being unable to speak. His stomach full and not a drop of the spaghetti left on his plate.

"Alright" Sans stood up and gathered the empty plates, putting them in the sink. Not bothering to wash them right now, "Do y'want me to grab the pillows?" Sans asked.

"pillows?" Papyrus glanced at his brother of whom was already going up the stairs. Having no patience to wait for an answer and within moments he had gotten all the cushions from their bedrooms and thrown them onto the couch.

Then disappearing as he goes to grab the big blanket from his wardrobe. Papyrus gets himself up, clinging onto his full stomach and making his way to the couch. His brother coming down the stairs carefully with the blanket.

"Come on lazy bones we gotta put the mattresses here yet!" Sans said wandering over to his brother and placing the blanket down to the side.

"wait sans..." Papyrus sat took a hold of his brother's arm, Sans stopped and looked at his brother with a confused look. _Had he done something wrong?_

"what's all this for?"

"Well if were watchin' a movie, I thought we should whilst... being comfy?" Sans said feeling more nervous as his brother looked at what he had gathered.

Papyrus thought for a moment his gaze now fixed on his brother. He didn't want to disappoint him and he had already gotten most everything.

"why not? it is a good idea after all"

Sans smiled, as he was praised though feeling silly for even thinking his brother was mad. His hand took a hold of his brothers jumper as he proceeded to practically drag his lazy brother up the stairs. The two working together managed to get both mattresses down stairs safely with his lazy bones brother using his magic!

When the now double bed was made and the TV was on they both chilled for a bit, letting their dinner go down and warming up under the duvet. It was really cosy, Papyrus made a mental note of doing this more often. Especially if Sans would continue being adorable by snuggling close to him.

"Papy i'm gonna go get my pyjamas on okay?" Sans said as he pulled away.

Papyrus nodded and watched as Sans walked up the stairs, "can you grab me a shirt?"

Sans turned around holding a thumbs up. _Stars he is too cute._

Papyrus took this time to have a smoke as he hadn't had one in a good few hours and steadily he could feel his nerves get the better of him. Though his brother hated them, they really took away any horrible unwanted feelings.

He waited patiently as his brother got changed then walking over to his room, he chuckled as Sans groaned and mumbled about how he'd only cleaned it yesterday. Wondering how his brother can make it such a mess. If only he could watched as Sans would almost dance to avoid getting any dirt on his feet, especially if nothing was covering them.

"Here" Sans threw down the shirt to his brother of whom caught it and promptly closed their bedroom doors before making his way downstairs.

He looked even more cute with his star covered pyjama set. Along with those cute buttons that looked immaculate despite him wearing it every night. Papyrus sighed and placed the cigarette to the side as he removed his jumper and shirt, throwing them both behind the couch somewhere and put on the fresh one.

Sans sat down on the covers and looked at the case. It had kissy cutie on it in a 'kawaii' pose as Undyne would say, her chainsaw in hand along with her friends behind her. It looked good but if Undyne leant this to them then maybe it wasn't? she is always paranoid about lending out her stuff, however the label...

"shall I put it on then?" Papyrus asked interrupting Sans' thoughts.

Sans nodded and gave him the case, watching as his brother gets up. He was so happy as they never spent time like this anymore. Papyrus always has work in the morning so he tends to go to bed rather early but seeing as though the storm wasn't letting up, Sans had a feeling that he wouldn't be needed at work tomorrow. Which was good because they could stay up longer.

Papyrus waited until he could press play on the dvd player, before getting into bed. Undyne never did find the remote so they had to do things manually.

When the movie started Papyrus was sat upright and leaning back against the couch. He glanced over at Sans and saw that he looked uncomfortable as though waiting to be allowed into the covers. Papyrus chuckled and pulled up said covers, patting on the mattress inviting his brother into them.

Sans smiled, taking up the offer and happily snuggling into his brother chest. He had gotten another cigarette by this point but it didn't matter as he was focused on the brightly coloured anime playing.

By this point the fire was weak but the two being in each others company helped to keep them warm.

"How was your day Papy?" Sans asked his eyes not straying from the anime.

"pretty slow, not many customers"

"Oh... well it must've been the bad weather..." Sans further cuddled into his brother hugging him rather tightly, sighing contently.

"what about your day? train with Alphys?" Papyrus said as he used his magic to grab a bottle of honey placed on the table side. He forgot to pick it up prior to sitting down.

"Pretty good! we went through a cooking book 'cause of the bad weather and I found the pasta recipe and since it looked so good I wanted to try and make it!" Papyrus watched his brother as he explained what shenanigans he and Alphys got up to and from the various expressions it seemed like a fun day for him. In fact he was half expecting his brother to fall asleep during the film but he was half focused on it and talking to him. _Such a sweetie._

"-and then I had to clean it all up! honestly..." Sans laughed as he recalled how horrified Undyne looked as she saw her walls covered in tomatoes, "She and Undyne are fun to be around"

Papyrus despite what Undyne claimed really wasn't a huge fan of this 'anime'. Too bright and over the top, besides it involved reading as it wasn't in a language that he understood and well, he was too lazy to read it all. Bits and pieces were fine, besides Sans would go through it all afterwards. Acting out a few scenes adorably.

Though he never recalled this kissy cutie character making out with anyone before or pushing them to the bed really roughly, wait when had they gotten to the bedroom? wasn't this about a girly girl that saved the day? why was she pulling down his... _shit._

Gulping nervously, Papyrus glanced down at Sans watching as he gripped the covers as it was happening. His own grip tightened on his cigarette as he heard the female moaning in the background. _Were the sinful gods testing him or some shit?!_

"Papy..." Sans started, "why is she making those noises?" Sans asked his brother with a curious glare.

"heh... what noises?"

Almost on cue a loud moan echoed throughout the room.

"Like that" Sans said looking rather smug as Papyrus nervous tugged at his shirt.

"i'm not sure sans just ignore it"

Sans furrowed his eyes but leaned back onto Papyrus' chest anyway. A tad frustrated that his brother was clearing not being honest, still it was nice to know that his brother would do this for him. Kinda.

"Do you think that she's lonely and needs a friend?"

"maybe" Papyrus put out his cigarette and finished drunk the rest of the honey. Placing an arm around Sans' shoulder pulling him closer, he truly loved Sans and his boundless kindness towards others. Something he strived to keep pushing him for even if it sometimes it didn't work...

"I would be her friend" Sans said lowly as he was more focused on the anime.

"yeah?" Papyrus rubbed the top of his brothers head and leaned down to kiss it causing Sans to blush a little but not to his brothers knowledge thankfully!

A little later on after the male character from before turned down her offer as he still had 'stuff to do'. Bit dramatic but that is the definition of this anime. He hoped that the suggestive stuff had finished but just as the action was over, the male pulled kissy cutie close saying in a seductive tone, "where were we?"

Oh shit.

Here we go again. Loud moans and groping- wait... tentacles? as if this could get anymore sexual. He really didn't dare to look down at Sans, if Sans looked remotely interested in this then he'd probably lose it himself.

But Sans seemed to fine considering the explicit details but then again his grip on his brother tightened with every moan, maybe he too was trying to hold something back, Papyrus could only hope that Sans wouldn't ask about this too.

_"Sensei...! ohh ahh~" Cutie kissy moaned as she was kissed lightly on her breast as the other was being rubbed._

_"You like this don't you my love?" The 'Sensei' character said between kisses. The tentacles from before held the girls arms down before rubbing, squeezing all of her sensitive spots. Mainly her breasts and neck._

The intense moans caused the two skeletons to shiver in unison.

Papyrus was lost in thought as he pictured his brother being kissy cutie and him being on top. Making his brother squirm like that, making him scream his name as he became undone.

"Papy..." Sans whispered his sight still set on the TV, "Why is he doing this?"

Papyrus shook those thoughts away, a bright blush on his cheeks. He cleared his throat and patted his brothers back, not sure of what to say but maybe if he stalled long enough then Sans would fall asleep, giving him time to think of a good answer.

"It looks strange..." he mumbled, "Is this what couples do together?"

Papyrus nodded slowly and looked down at his curious brother. Seeing his cheeks a light blue and hand resting on his chest to keep himself upright.

"Oh..." Sans said, now fiddling with his brothers shirt as though contemplating something, "Is it... _just_ couples?"

Papyrus sighed, his brother was catching on. But that was Sans always noticing the small details and dragging them out to be huge. Never relenting until given an answer that he was satisfied with.

"look sans..."

"Can we do that?" Sans asked his eyes bright and brimming with stars.

Papyrus shook his head feeling guilty as his brother frowned. But settled back onto his chest, clearly disappointed.

They watched the rest of the movie, it was dramatic as ever as a new villain was introduced as it finished.

"so... what now?" Papyrus asked shaking Sans' arm gently.

Sans sat upright and looked at his brother, his eyes looking into his own. His smile wasn't present which only added to the guilt. But it was wrong and maybe he should just explain this to him, even if it was something he craved for. He just... didn't deserve that level of love with Sans, he only deserved the love that brothers should share nothing more. Sans was just confused and when he finds his mate then... then he'll understand why it wouldn't have ever worked.

"do you wanna watch another?" Papyrus smiled weakly watching as Sans looked over at the pile of dvds.

"Mm... nah..." Sans sighed, "but... can we talk in the dark like we used to? remember? back in the capitol"

"yeah..." Papyrus said.

Their old life in the capitol. Poor and living in a run down apartment complex with no money for electricity but they always had food and somewhere to sleep. Sans always made sure of it. Papyrus has maintained that admiration for his brother, being able to provide for them both even if the *work he did wasn't... stable.

He got up and turned the TV off, being careful not to stand on Sans and not bump into anything as he carefully got back into the bed, getting comfortable he lay down with one hand behind his head and the other wrapped around his brother.

"I love you... y'know?" Sans titled his head up to his brother a hand rubbing his chest.

"i know sans... i love you too" Papyrus smiled, it was true after all.

"So why can't we be like that?" Sans asked his arm supporting his head whilst he looked at Papyrus, his other hand still rubbing his brothers chest.

Papyrus sighed and closed his eyes before looking at Sans, "sans we just can't"

Sans frowned his hand withdrawing from his brother's chest. Instead he rolled over, covering his eyes. Papyrus' soul ached as his brother did his best to not sob but his body was still shaking and his teeth scrapped against one another.

"we're brothers sans... we can't love each other like that" Papyrus said not knowing if his brother was listening but spoke anyway hoping that he was, "someday when you meet a monster. someone you love and cherish. someone that makes your soul flutter with every small gesture they do... then you'll understand what love really is"

Sans stopped moving as he spoke listening to his words. But it almost made him laugh at how easy he could connect those words to his brother. He loved and cherished Papyrus, his soul always fluttered whenever he would smile or even pat his head telling him how cool he was. He knows what love is and for a long time has wanted to express that said love with him.

But if Papyrus didn't want that love then he wouldn't force him.

"Papyrus... don't you understand?" Sans turned towards his brother again freely allowing tears to fall down his cheeks, "you meet all those standards... and their really isn't anyone who i'd want to share my life with... won't you let me love you?" Sans rested a hand on his brother's cheek, gently rubbing it.

"but... sans..."

"Please?" Sans leaned in closer to his brother holding him close, resting his head on his chest.

"are... you sure?"

Sans nodded a small smile on his face as he made small circles on his brother's chest with a finger.

"certain?"

"Mwehehe yes Papyrus"

Sans felt his brother's arms immediately twist around so that they held his small body once again bringing them close together. He welcomed the embrace as he nuzzled into his brother, sighing contently from their closeness.

Papyrus on the other hand felt uncertainty. Did his brother truly understand what he was doing? Had he fallen asleep and was this all a dream? He needed to be sure and so moved his hand up Sans' shirt and slowly caressing one of his lower ribs.

If his brother showed any sign of discomfort than he'd stop.

Instead his brother groaned from the touch his body withering slightly from it. He leaned up towards his brother, of whom contemplated stopping as his movements slowed. Sans closed his eyes and gently kissed Papyrus a hand stroking his cheek again in a circular motion.

Those movements started again as they kissed. One hand moved further up Sans' back and rubbed a rib that was close to his soul though slowly and carefully. Sans groaned, shakily reaching for his brother's hand encouraging it to go faster, rougher.

"Mm.. papy..." Sans moaned.

Papyrus pulled back for a moment, looking his brother in the eyes. Taking a hold of the hand that held his cheek and kissing it lightly. He grinned as his brother's body shivered, his hands always being sensitive to touch.

Taking a hold of that hand he leaned down to Sans' neck kissing each vertebrae with care. To further access Sans tilted his head up forcing his eyes shut as his neck was assaulted with gentle kisses and rib being caressed.

"P- papy..."

"mm what?" Papyrus hummed licking a particularly sensitive vertebrae causing Sans to moan loudly, hands holding onto his shoulders for dear life panting though not needing air.

"F... faster... please"

Papyrus pulled back again and looked at his brother.

"stars sans..."

Papyrus nodded to himself and moved the covers back so he could finally view his older brother's small frame. Positioning himself on top with his arms at both sides of his brother's head.

His eyes showed nothing but pure trust even as Papyrus' hand was close to his soul. _His fragile soul._

"Papyrus...?" Sans hoped his brother wasn't having second thoughts again. As he stared down at him.

Papyrus sighed as his hand rubbed his brothers cold, blue cheek. Watching as Sans nuzzled into it like the cat that would sometimes pay them a visit. But clearly Sans craved the attention more as he kissed it tenderly.

"so... your certain?"

Sans stopped kissing his hand but put his own over it, "Yes Papy... I love you... I love you so much... please... love me too"

He jumped a little as Papyrus kissed him but with more confidence as he opened his mouth showing his tongue and scrapping it against Sans' mouth. To which he complied allowing that new, slithering appendage to move around his mouth. In particular pressing against a spot at the top of his mouth which always drove him insane. Wanting to taste that appendage properly Sans formed his own though smaller and thicker it was physical. It was also a little tricky to control but Papyrus seemed experienced as it moved and intertwined with his own with ease.

Such a bittersweet taste that he couldn't help but melt into, a moan echoing through his mouth and into his beloved brother's, causing him to growl for more. Greed getting the better of his judgement he hastily undid the buttons to Sans' adorable pyjamas moving it so he could stroke those delectable ribs.

He pulled away from the kiss, looking down at his panting and increasingly needy brother as he whined from the loss of contact. But he just couldn't help but look at those ribs, so thin and fragile, in need of attention.

"Papy... please..." Sans shyly covered himself from his predators hungry gaze only for him to move them away with one of his hands.

"yes?" Papyrus said though not removing his sight from those ribs.

"I... I want... oh~"

Sans moaned as his brother, unable to wait delve into his ribs, licking the one closest to his soul. Wrapping his long tongue around it, allowing his saliva to drip onto his soul.

With each drop of saliva that fell onto his soul, he arched his spine and moaned louder. Papyrus couldn't help but moan also as Sans called out his name.

"Papy... no... no more... Aaah~"

Papyrus grinned as he removed a hand to wrap around his spine. Rubbing carefully between his intervertebral, being careful to not cause any harm to his sweet lover.

"Please! just... just..." Sans felt his hands being released and though he could fell his brother continue to stroke his spine, he had moved back and was tugging at his pants.

"is... this okay?"

"Yes! mm~ please! please! please just..." Sans begged, looking at his brother, tears threatening to fall at any moment.

Papyrus smiled again and removed his wet pants, throwing them aside. He removed his hand away from his spine and felt around the dripping cunt that his brother formed for him.

So sensitive and throbbing as he needed that feeling, he didn't know what feeling exactly but Sans knew something was amiss, as though he needed to be filled. He needed Papyrus now!

He squeaked as his brother lowered himself, grabbing a hold of his legs and resting them of his shoulders. He was going to question what he was doing but his body shook as Papyrus opened his mouth, that expertly controlled tongue licking his cunt.

"Papyrus! oh~ stars" Sans moaned as one hand gripped the covers feverishly and the other reaching for his brother's head, gently pushing it down. Begging for more.

Papyrus happily continued his assault on his brothers sweet entrance, licking his inner walls, searching for the spot that would no doubt cause him to scream. Oh how he wanted to hear it.

Unconsciously or not but the way his brother would clench those walls around his mouth was going to make him cum before long. Such a divine treat that he'd craved for so long. Such a sight that he'd only dare to fantasize about, now here before him.

Each moan, gasp and shout of his name was such a wonderful sound that he couldn't get enough off. So when Sans panted about being close, he carefully withdrew himself.

He may be selfish doing this but he had his own need to satisfy. He chuckled as Sans whined and begged him to let him release, to not stop. He crawled up closer to his whimpering brother and kissed his cheek.

Feeling his brother wrap his small arms around him, whispering to him just how much he loved him. Watching him as he removed his shorts, carelessly throwing them to side, his member being in view he grinned as Sans gasped. Drooling as Papyrus stroked it, smothering the pre-cum over it.

"are you ready sans?"

Sans gulped but nodded and watched as Papyrus lowered himself a little further down. Once again raising one of his legs for better leverage and teasingly rubbing his cock around that stretched, aching cunt.

One of his hands was intertwined with Sans' gripping tightly as he eased himself into his little brother, watching Sans' face. Being sure that he wasn't going too fast, even if his body desperately begged for him to move faster.

He waited for Sans to adjust to his cock before moving further in, hissing as his walls clenched around his cock.

"f- fuck!" Papyrus groaned as his cock filled his brother.

Sans panted as his brother pulled out to then fill him again. His thrusts becoming steadily faster as his cunt stretched further to accommodate his dick, he quickly became aware of how better it was when he moved his hips also. So as his brother thrusted into him he rolled his hips and found a rhythm, his brother moaning loudly, praising him for doing so good made him feel so close again.

"Oh papy~ papy~" Sans moaned.

"s- sans~"

With one particular thrust Sans cried out in ecstasy. Finding his g-spot Papyrus grinned as he hit it over and over, Sans' moans getting progressively louder. Unable to think as his mind became hazy from such an over-load of pleasure.

"Papy... what... what is... oh~ ah~" Sans looked up at Papyrus for reassurance as his body trembled as though it he needed to release.

Papyrus smiled down at him, "it's okay... just let it happen"

Sans nodded as papyrus thrusted against that spot again, finally tripping him over the edge, "Aah~ Papy~" he screamed as he orgasmed.

His walls tightening around Papyrus' cock edged him to his orgasm also, "fuck s- sans! i'm... i'm gonna... fuck!"

Sans panted hard as his brother released into his sensitive cunt. His thrusts slowing until he stopped. Eventually and with care he pulled himself out of his brother, putting down his leg and lay next to him.

They both lay their for a moment to rest. When Sans started to shake Papyrus brought up the cover over them both. Laying on his side he pulled Sans close to him and waited until he stopped shaking.

"stars, sans... you were amazing..." Papyrus said as he planted a kiss on his brother's head.

"I love... you" Sans smiled, letting out a yawn.

"heh... i love you more~" Papyrus stroked Sans' head until his breathing calmed before letting himself fall asleep.
